Identity theft reports to the Federal Trade Commission show that Verizon was the most frequently named company, averaging over 900 events per month in 2007. According to an updated study by Chris Hoofnagle, senior fellow at the Berkeley Center for Law and Technology, the number of complaints involving Verizon nearly tripled from 2006. Rounding out the top five are AFNI (a collection agency), JP Morgan Chase, AT&T, and Capital One.
